Types

type Block

type Block struct {
	// contains other fields, but this ones are the important to us right now...
	Hash   string  `json:"hash"`
	PHash  string  `json:"parentHash"`
	Number string  `json:"number"`
	TS     string  `json:"timestamp"`
	Tx     []Trans `json:"transactions"`
}

Block contains a simplified list of block fields.

type Token

type Token struct {
	Name     string      `json:"name"`
	Symbol   string      `json:"symbol"`
	Decimals uint8       `json:"decimals"`
	Data     interface{} `json:"data"` // contains specific chain details
}

Token is a blockchain asset.

type Trans

type Trans struct {
	Block  string `json:"block"`
	Hash   string `json:"hash"`
	From   string `json:"from"`
	To     string `json:"to"`
	Token  string `json:"token,omitempty"`
	Value  string `json:"value"`
	Data   string `json:"data,omitempty"`
	Gas    string `json:"gas"`
	Price  uint64 `json:"price"`
	Fee    uint64 `json:"fee"`
	Status uint8  `json:"status"`
	TS     uint32 `json:"ts"`
}

Trans contains a simplified number of transaction fields. For the time being, we keep just one transfer from `From` to `To` but there are blockchains that have multiple transfers in one transaction.
